Cajun M770 ATM Switch User’s Guide 1
Chapter 1
Introduction
This chapter provides information about the Cajun™ M770 ATM Switch, and the
features that this software release supports.
Note: This User Guide describes only the ATM functionality of the Cajun M770
chassis.
About the Cajun M770 ATM Switch
The M770 ATM switch is a high-performance distributed Asynchronous Transfer
Mode (ATM) switch that is designed for building and campus backbone
applications, high-performance centralized servers, and power-user environments.
Its advanced architecture can support very high traffic loads with no data loss or
breaks in communication. The M770 ATM Switch also implements LAN Emulation
(LANE) components. LANE enables legacy LAN applications to use a transparent
ATM transport medium. In this way, end-stations on existing LANs can
communicate with ATM end-stations.
The M770 ATM Switch supports a range of option modules that enable you to
customize the switch to fulfil applications that are appropriate to your networking
requirements. It is designed as a software-upgradeable product. Therefore, you can
expand the functionality of the switch by downloading new software.
• Information about the Cajun M770 chassis’ safety considerations, architec-
ture, main chassis control panel, M-SPV/M-SPX/M-SPS supervisor modules,
power supplies and fans is available in the Cajun M770 User Guide.
• Detailed information about the 10M/100M/1Gigabit Ethernet, M-SPV/M-
SPX/M-SPS supervisor, and M-MLS multilayer module can be found in their
respective Installation Guides

Master Agent and Sub Agent
The M770 ATM Switch is a fully distributed ATM switch. Each module has its own
switching and CPU power. In order to present the switch as a single and united
entity, one module is automatically elected as a Master Agent while the other
modules are Sub Agents. The Master Agent status is shown by the Network
Management Agent (NMA) LED.
The Master Agent is the module hosting the Management LEC with all its
functionality: IP address and switch-wide information. The Master Agent is also a
regular module with all the functionality of a Sub-Agent such as controlling the
physical ports, virtual ports and download.
The Master and Sub Agents have slightly different CLI options. For example, the
Master Agent has the “ip” command and the “access” command which will enable
you to access a Sub Agent from the Master Agent. A simple way to find out
whether you are currently communicating with a Master Agent is to type “help” at
the command line and check whether there is an “access” command option.
All the information configured to the Master Agent (IP, ATM Prefix) is backed up
by all the Sub Agents, so if the Master Agent is removed, another module will be
elected and all previous configuration settings will be kept.
